Prospective studies have shown equal outcomes after mastectomy or breast conservation in patients with invasive breast cancer; however, many of these studies excluded elderly patients. We identified patients in their eighties and nineties with clinical stage 0 to II breast cancer undergoing mastectomy or lumpectomy with or without radiation from the prospective sentinel lymph node database at Wake Forest Baptist Health and analyzed their treatment and survival. Of 92 patients, 24 (26.1%) underwent mastectomy, 22 (23...

Breast conserving therapy (BCT), lumpectomy followed by radiotherapy, is an effective treatment for a majority of breast cancers. According to the National Comprehensive Cancer Network, mammographic imaging should be completed at least six months after completion of radiation. This study evaluates the clinical significance and financial cost of postoperative breast imaging within one year of BCT. Patients treated with BCT between 2014 and 2016 at an academic center were identified retrospectively. The medical records were reviewed to identify the timing and type of the first imaging study after BCT...

To evaluate acoustic radiation force impulse (ARFI) inthe differential diagnosis of small (≤20 mm) solid breast lesions and identify the most efficient ARFI parameters. Conventional ultrasonography and ARFIwere performed in 120 patients with 121 small solid breast lesions. The area ratios (ARs) of the lesion on virtual touch tissue compared to B-mode were calculated. The shear wave velocity of the inner (SWVi) and boundary (SWVb) of the lesions and surrounding fatty tissue (SWVf) was measured. The ratio of SWVi to SWVf (SWVrat) was calculated...

OBJECTIVE: The clinical effectiveness of targeted intraoperative radiotherapy (TARGIT-IORT) has been confirmed in the randomised TARGIT-A (targeted intraoperative radiotherapy-alone) trial to be similar to a several weeks' course of whole-breast external-beam radiation therapy (EBRT) in patients with early breast cancer. This study aims to determine the cost-effectiveness of TARGIT-IORT to inform policy decisions about its wider implementation. SETTING: TARGIT-A randomised clinical trial (ISRCTN34086741) which compared TARGIT with traditional EBRT and found similar breast cancer control, particularly when TARGIT was given simultaneously with lumpectomy...

PURPOSE: We examined the utility of echocardiographic 2-dimensional speckle tracking strain imaging (SI) for the evaluation of segmental myocardial dysfunction before and after radiation therapy (RT) and the relationship to dose exposure. METHODS AND MATERIALS: We prospectively recruited 40 women with left-sided breast cancer, undergoing only adjuvant RT to the left chest. Comparisons of traditional echocardiographic parameters and SI parameters at baseline and 6 weeks after RT were analyzed...

PURPOSE: To determine whether adjuvant radiation therapy (RT) is associated with adverse patient-reported outcomes and surgical complications 1 year after skin-sparing mastectomy and immediate autologous free flap reconstruction for breast cancer. METHODS AND MATERIALS: We compared 24 domains of patient-reported outcome measures 1 year after autologous reconstruction between patients who received adjuvant RT and those who did not. A total of 125 patients who underwent surgery between 2012 and 2015 at our institution were included from the Mastectomy Reconstruction Outcomes Consortium study database...

PURPOSE: Treatment with checkpoint inhibitors has shown durable responses in a number of solid tumors, including melanoma, lung, and renal cell carcinoma. However, most breast cancers are resistant to monotherapy with checkpoint inhibitors. Radiation therapy (RT) has been shown to have a number of immunostimulatory effects, including priming the immune system, recruiting immune cells to the tumor environment, and altering the immunosuppressive effects of the tumor microenvironment. RT therefore represents a promising adjuvant therapy to checkpoint blockade in breast cancer...

PURPOSE: Radiation therapy (RT) is associated with high stress levels. The role of music therapy (MT) for patients receiving RT is not well described. This study evaluates the impact of MT on anxiety and distress during simulation in patients with newly diagnosed head and neck or breast cancer. METHODS AND MATERIALS: This institutional review board-approved randomized trial of MT versus no MT at the time of simulation included the pre-State-Trait Anxiety Inventory (STAI-S Anxiety) questionnaire and Symptom Distress Thermometer (SDT)...

A survivin-associated radio-adaptive response, characterized by increased radiation resistance or sensitization, was induced by exposure to 5 mGy of ionizing radiation and was correlated to the TP53 mutational status of exposed cells. Ten human cancer lines were investigated: colorectal carcinomas HCT116 and RKO [TP53 wild-type (WT)] and their respective TP53 null isogenic lines; breast adenocarcinomas MCF7 (TP53 WT) and MDA-MB-231 (TP53 Mut); lung carcinomas A549 (TP53 WT) and NCI-H1975 (TP53 Mut); and pancreatic carcinomas Hs766T (TP53 WT) and Panc-1 (TP53 Mut)...

Melanoma is the third most common cause of brain metastases, after lung and breast cancer. The management of melanoma brain metastases can be broadly divided into symptom control and therapeutic strategies. Supportive treatments include corticosteroids to reduce peritumoral edema, antiepileptics for seizure control, and medications to preserve cognitive function. Until recently, therapeutic strategies consisted primarily of local treatments, including surgery, whole-brain radiation therapy (WBRT), and stereotactic radiosurgery (SRS)...

BACKGROUND AND PURPOSE: To explore the methods of clinical classification in chronic radiation-induced ulcers in the chest wall (CRUCWs). MATERIALS AND METHODS: A total of 64 patients with CRUCWs were treated. We divided the cases into 3 types (mild, moderate, or severe) according to their clinical manifestations. Conservative treatments, axial-pattern myocutaneous or local flaps, or filleted flaps were applied correspondingly. RESULTS: The cases were divided as follows: mild (n = 11), moderate (n = 45), and severe (n = 8)...

BACKGROUND: Little is known about how the individual decision styles and values of breast cancer patients at the time of treatment decision making are associated with the consideration of different treatment options and specifically with the consideration of contralateral prophylactic mastectomy (CPM). METHODS: Newly diagnosed patients with early-stage breast cancer who were treated in 2013-2014 were identified through the Surveillance, Epidemiology, and End Results registries of Los Angeles and Georgia and were surveyed approximately 7 months after surgery (n = 2578; response rate, 71%)...

The relative biological effectiveness (RBE) of neutrons depends on their physical nature (e.g., energy) and the biological context (e.g., end points, materials). From the perspective of radiological protection, age is an important biological context that influences radiation-related cancer risk, but very few studies have addressed its potential impact on neutron effects. We therefore investigated the influence of age on the effect of accelerator-generated fast neutrons (mean energy, ∼2 MeV) in an animal model of breast carcinogenesis...

PURPOSE: As elective axillary dissection is loosing ground for early breast cancer (BC) patients both in terms of prognostic and therapeutic power, there is a growing interest in predicting patients with (nodal) high tumour burden (HTB), especially after a positive sentinel node biopsy (SNB) because they would really benefit from further axillary intervention either by complete lymph-node dissection or axillary radiation therapy. METHODS/PATIENTS: Based on an analysis of 1254 BC patients in whom complete axillary clearance was performed, we devised a logistic regression (LR) model to predict those with HTB, as defined by the presence of three or more involved nodes with macrometastasis...

PURPOSE: Aromatase inhibitors (AI) have been shown to reduce breast cancer-related mortality in women with estrogen positive (ER+) breast cancer. The use of AIs, however, has been associated with higher rates of hypertension, hyperlipidemia, and cardiovascular (CV) events. METHODS: A cross-sectional study of 25 healthy postmenopausal women and 36 women with curative intent breast cancer on an AI was performed to assess endothelial dysfunction, an indicator of risk for CV events...

Radiation therapy (RT) can be lethal to a developing fetus; therefore, determining pregnancy status before RT is essential. We here sought to determine how many women treated with RT at our institution for over one year were at risk for pregnancy when starting RT. We retrospectively reviewed the medical records of all female patients 12-55 years old treated with radiation, i.e. 1 October 2012 to 31 September 2013. Patients were categorised as 'at risk' if they had a uterus and 'no risk' if they had a hysterectomy...

CONTEXT: Most of the reviews on the biological basis for symptom clusters suggest that inflammatory processes are involved in the development and maintenance of the symptom clusters. However, no studies have evaluated for associations between genetic polymorphisms and common symptom clusters (e.g., mood disturbance, sickness behavior). OBJECTIVES: Examine the associations between cytokine gene polymorphisms and the severity of three distinct symptom clusters (i...

Delivering an adequate and homogenous dose to a large volume of recurrent cutaneous disease can be challenging even with modern techniques. Here, the authors describe a 3-isocenter hybrid electron and rapid arc photon radiation treatment plan to provide optimal tumor coverage to an extensive recurrence of inflammatory breast carcinoma. This approach allowed for homogeneous treatment of a large volume while effectively modulating dose to previously irradiated tissue and minimizing dose to the underlying heart, lungs and brachial plexus...

PURPOSE: Breast conserving surgery (BCS) has become the preferred surgical option for the management of patients with nonmetastatic breast cancer in high-income countries. However, little is known about the distribution and determinants of BCS in low-and middle-income countries, especially those with high HIV prevalence. METHODS: We compared demographic and clinical characteristics of female patients who received BCS and those who received total mastectomy (TM) for nonmetastatic invasive carcinoma of the breast in Soweto, South Africa, 2009-2011...
